Afghan Taliban leader Mullah Mohammad Omar has been killed in Pakistan, a private television channel reported Monday.

"Mullah Omar was killed on way from Quetta to North Waziristan, " TOLO television said in its news bulletin.

However, it did not provide details on how he was killed and by whom.

Meanwhile, a security official confirmed the killing, saying, "it is correct that Mullah Omar has been killed."

The official emphasized that Mullah Omar was killed inside Pakistan.

Taliban militants fighting Afghan and NATO-led troops in Afghanistan have yet to make comment.

Mullah Omar has survived massive U.S. military manhunt since the collapse of Taliban regime by U.S-led invasion in late 2001 for sheltering al-Qaida chief Osama Bin Laden.

U.S. commandos killed Bin Laden in a raid on his hideout in Pakistan on May 2.
